PAQTENIED FEB. 16, 1858. P. MQGHAN. WATER CLOSET,-

UNITE AES WATER-CLOSET.

Specification of Letters Patent No. 19,375, dated February 16, 1858.

To all whom 'it may concern:

Be it known that I, FRANCIS MCGQHAN, of Vashington city and District of Columbia, have invented a new and useful Improvement in ater-Closets; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, forming part of this specification, in which- Figure 1 is a top view of closet with seat removed to show water apparatus. Fig. 2 is a front elevation with casing broken out. Fig. 3 is a section on lines w a; and y 3 Similar characters of reference in the several figures denote the same part.

The nature of my invention consists in a peculiar construction for regulating the flow of water to pan closets, for cleansing them after use.

In the drawing B is the basin, P is the pan hung upon shaft a, and C is the waste chamber with discharge pipe leading therefrom. lVater flows to the basin through the pipe A, discharging therein at b (Fig. 3). The other mouth of this pipe is in plate 0, against which the elastic diaphragm valve f acts. The head of water is conveyed through pipe I whose mouth is closed by the metallic center of valve f, as shown in Fig. 3. Behind the rubber diaphragm of the valve is a metallic disk 2' of greater diameter than the center piece 6 against which the head of water actsto force back the valve and establish a flow through pipe A, to the basin. Behind the valve is a chamber D, entirely closed except at top where the pipe m enters. This pipe in in communication with the waste chamber C, by channel a, thus giving an outlet from chamber D into the waste chamber. This communication is regulated by a valve 11 at the lower end of rod 1*, so that when the valve rests upon its seat, as shown in Fig. 3, the flow of water from chamber D will be stopped. There is an elastic diaphragm packing 2) attached to the rod r and'pipe m, to prevent water passing out the mouth of the pipe, and aid in returning the valve to its seat. The rod is attached to lever Z, whose fulcrum is at and which by reason of weight to at the extremity of its long arm, has a tendency to keep valve 41 upon its seat, as shown in Fig. 2. Lever Z is actuated by lever L, whose long arm is lifted by power applied to handle it of rod 9, the weight to at its extremity returning it to the position shown in Fig. 2 when this power is removed.

A stud s on long arm of lever L works in the slotted arm a of shaft a, to tilt the pan when the handle 72 is lifted. This lifting of the handle it is the ordinary operation after using pan closets. Its effect upon this construction is to discharge the contents of the pan, and permit a portion of the contents of chamber 1) to be forced into the waste cham ber C.

Through the center of the valve f is an aperture 0, the size of which is regulated by a screw is, as seen in Fig. 3. The effect of this opening is to furnish a gradual supply of water to chamber D, the time of filling which will depend on the size of the openlng.

Then the chamber D is filled with water, there will exist a pressure of the full head through pipe I against the disk 2', and since this disk is greater in diameter than plate 6 against which the direct pressure of the head of water is brought, the valve f is forced against plate 0, and the mouth of pipe I stopped by plug 6.

This is the condition of the apparatus prior to use, immediately after which the handle it is lifted. This operation as above stated, opens valve 1) simultaneously with the tilting of the pan, which permits the pressure against plate 6 to force back the elastic diaphragm f and permit the flow of water through pipe A to the basin, the displaced contents of chamber D passing to waste chamber C. The handle it drops the instant the hand of the operator is withdrawn, restoring all parts to their proper condition, while the flow of water through pipe A continues until suflicient water has passed through opening 0 to force the valve against plate 0. This length of time depending on the dimensions of the said adjustable opening.

Having described my invention, what I claim and desire to secure by Letters Patent is The chamber D behind valve f in adjustable communication with the water head, and having a waste discharge by the operation of the lever tilting the pan substantially as, and for the purpose set forth.

In testimony whereof, I have hereunto signed my name before two subscribing wit- 110 nesses.

FRANCIS MGGHAN.
